Apple is widely expected to release its iTunes Radio streaming service sometime next month. The service was first announced back in June at Apple's WWDC conference and we have known that the free service will be made possible by the injection of ads. Today, we found out what type of ads those will be.

According to website TechSpot, Apple injects three different types of ads into the free version of the streaming service. An audio ad will play every 15 minutes, while a video ad will queue up every hour, and finally the third type of ad is what is known as an interactive "slate" advertisement, which fully consumes the entirety of the display. All three of these ads will be present on the iPhone, iPad, and desktops or laptops running iTunes. It is said that users of Apple TV will also experience similar ads.

Circumventing these ads is quite simple and requires users to purchase an iTunes Match subscription, which will remove all advertisements from the service. In the beginning, the ads will run across all platforms, but later in 2014, advertisers will have the ability to specify specific devices on which they wish their ads to appear. This means that someone advertising iPhone accessories will be able to target their ads to only display on iPhone devices.
